Spring Garden Care in the UK

UK Weather Conditions in Spring

Spring in the UK, from March to May, is marked by gradually increasing daylight, temperatures averaging between 8°C to 15°C, and frequent rain showers. It's a time of awakening for plants, making it the perfect season for rejuvenating soil and encouraging strong early growth.

Key Gardening Tasks

• Soil preparation

• Early sowing and planting

• Fertilising to support new growth

• Weed control

Growmore General Purpose Fertiliser

Apply 100-150g per square metre to flower beds and vegetable patches. This fertiliser features a balanced NPK ratio of 7-7-7, making it ideal for broad-spectrum support of early growth in lawns, vegetables, and ornamental plants. The nutrients are released gradually, feeding plants consistently and reducing the need for frequent reapplication. Its granular form makes it easy to spread evenly. By delivering a controlled nutrient release, it significantly reduces nutrient leaching and environmental impact, making it a sustainable choice for springtime feeding.

Fish, Blood & Bone Fertiliser

Use 70g per square metre and apply evenly around flower beds and root zones. This organic fertiliser is a time-tested combination that promotes early season growth by providing essential macronutrients in a slow-release format. Rich in natural proteins and trace minerals, it enhances soil biodiversity and strengthens root systems. Its organic origin ensures long-lasting fertility without the risks of overfeeding, and its biodegradable composition supports a healthy soil ecosystem over time.

Bone Meal Organic Fertiliser

Apply 75g per square metre near the base of shrubs and perennial plants. This phosphorous-rich organic fertiliser stimulates root growth and encourages early blooming. Its slow nutrient release supports sustained root development, making it ideal for establishing new plantings in early spring. Derived from natural bone matter, it decomposes gradually and contributes to long-term soil health while maintaining eco-conscious garden practices.

Compost Activator

Mix into compost heaps to accelerate the decomposition of organic matter. This product contains a nitrogen-boosting blend that feeds beneficial microbes, leading to faster breakdown of garden and kitchen waste. Enhanced composting not only reduces waste but enriches garden beds with organic matter that improves soil structure and water retention. Supporting your compost pile with this activator contributes directly to circular, sustainable gardening.

Summer Garden Care in the UK

UK Weather Conditions in Summer

From June to August, UK summers can be warm and dry, with average temperatures ranging from 15°C to 25°C. Water management and continued feeding are essential for maintaining growth and ensuring a good harvest.

Key Gardening Tasks

• Frequent watering

• Feeding flowering and fruiting plants

• Pest control

• Lawn care and mowing

Pro Grower Flower Fertiliser

Apply 80g per square metre every 4 weeks. Specially formulated for flowering plants, this fertiliser delivers high levels of potassium to promote prolonged blooming and vibrant flower colours. The inclusion of micronutrients supports stem strength and petal development, making it an ideal mid-season feed. Its targeted formulation reduces nutrient runoff, ensuring that every gram is used efficiently by your plants.

Pro Grower Fruit Fertiliser

Feed 90g per square metre to fruit-bearing plants like apples, strawberries, and currants. This fertiliser contains a high potassium-to-nitrogen ratio, promoting plump, sweet fruits while enhancing plant resilience during hot, dry weather. Micronutrient enrichment ensures balanced nutrition and helps prevent fruit drop. Efficient uptake reduces waste and supports water conservation efforts in home orchards.

Urea Prills Fertiliser 46%

Apply 30-50g per square metre to fast-growing summer crops. This highly concentrated nitrogen fertiliser encourages rapid leaf and shoot development, perfect for leafy greens and lawn repair. Its prilled form allows for uniform distribution, and its efficient nitrogen delivery minimises losses from volatilisation, ensuring better nutrient use efficiency and fewer environmental side effects.

Potassium Chloride

Apply 50g per square metre during the fruit set stage. Potassium Chloride is key to improving drought resistance and enhancing fruit quality by increasing sugar synthesis and firmness. Its contribution to water regulation within plants makes it essential during hotter months. With proper application, it boosts yield and reduces the risk of nutrient imbalances, maintaining soil harmony.

Autumn Garden Care in the UK

UK Weather Conditions in Autumn

Autumn in the UK runs from September to November with decreasing temperatures (around 10°C to 15°C), shorter days, and increased moisture. It’s the season for preparing your garden for winter dormancy and ensuring soil fertility for spring.

Key Gardening Tasks

• Mulching and composting

• Planting autumn bulbs

• Soil enrichment

• Lawn repair and treatment

Volcanic Rock Dust Organic Fertiliser

Apply 100g per square metre to garden beds and compost heaps. This natural mineral powder is rich in essential trace elements such as magnesium, calcium, and silica, which are often depleted in intensively cultivated soils. Volcanic rock dust replenishes these minerals, improving plant nutrient uptake and enhancing overall soil vitality. Its organic nature and slow-release mechanism make it a powerful tool in regenerative gardening.

Iron Sulphate Heptahydrate

Use 30-50g per square metre on lawns to green up and eliminate moss. This compound supports strong chlorophyll production, ensuring lush green grass during the colder months. Additionally, it helps to acidify alkaline soils slightly, increasing nutrient availability and microbial activity. A sustainable choice for lawn repair and turf health in the wet autumn months.

Dried Blood Organic Fertiliser

Apply 60g per square metre to vegetable beds and ornamental borders. As a fast-acting nitrogen source, dried blood supports late-season leafy growth and enriches soil with organic compounds. It stimulates microbial populations that break down organic matter, resulting in better nutrient cycling. This makes it ideal for preparing the garden for a productive following year.

Hoof and Horn Organic Fertiliser

Add 70g per square metre to overwintering vegetable beds. This slow-release fertiliser is a rich source of organic nitrogen, gradually releasing nutrients over several months. Perfect for long-term soil enrichment, it supports soil structure and fertility without the risk of leaching. Its natural origin ensures compatibility with eco-friendly gardening practices.

Winter Garden Care in the UK

UK Weather Conditions in Winter

Winter (December to February) in the UK is cold and damp, with average temperatures between 0°C and 7°C. Though growth slows, this is a vital period for soil conditioning and planning the year ahead.

Key Gardening Tasks

• Soil conditioning

• Winter composting

• Protection of perennials and bulbs

• Planning crop rotations

Ammonium Sulphate

Apply 25-40g per square metre, especially to alkaline soils. This nitrogen-rich fertiliser also serves as a soil acidifier, improving nutrient availability in high pH soils. It aids in early root development and supports microbial activity even in cold conditions, helping your soil wake up early in the spring. Its efficiency makes it a go-to fertiliser for winter maintenance.

Mono Ammonium Phosphate

Use 40-60g per square metre in polytunnels, cold frames, or greenhouses. This dual-nutrient fertiliser combines nitrogen and phosphorus to support root development and early plant vigor. It is particularly effective in seedbeds due to its low salt index, making it safe for delicate roots. A valuable addition to any winter gardening regimen.
